Tyson Fury's trilogy fight with Deontay Wilder is set to be pushed back until October.
Bob Arum, who is Fury's co-promoter in the United States with Frank Warren, said there is no chance the third bout between the pair will go ahead on July 18 due to the coronavirus pandemic.
When asked about the possibility of staging the fight as planned, Arum told ESPN: 'Clearly not. We don't even know if the MGM will even be open by then.
Fury beat Wilder in February to secure the WBC heavyweight title after their first encounter in 2018 had ended in a controversial draw.
Wilder activated a rematch clause in his contract to fight Fury for a third time, with the MGM Grand in Las Vegas scheduled to host the heavyweight title fight.
